Abstract
In this study, we report the first documented case of predation by Leptodeira approximans on Hyloscirtus dispersus, a hylid anuran with an Andean-Amazonian distribution, recorded in southeastern Ecuador. Leptodeira approximans was observed capturing and attempting to ingest an individual of H. dispersus while perched on a low shrub. Although the snake ultimately released the frog—presumably due to the presence of observers—the anuran exhibited signs of hemorrhaging, possibly caused by the colubrid’s venom.
